Abstract: APPARATUS FOR ELECTROCHEMICALLY FORMING A PLURALITY OF ARTICLES An improved apparatus for forming a plurality of airfoils or other articles includes a plurality of pairs of electrodes which are utilized in the electrolytic removal of material from opposite sides of a workpiece at a plurality of spaced apart locations to form side surfaces of a plurality of airfoils.  The electrodes are constructed so that a group of airfoils is formed along each of a pair of opposite minor sides of a workpiece.  In one specific instance, a plate having the configuration of a rectangle is utilized.  This plate may have a size such that only one end portion of the plate will fit in a working chamber at a time.  After a plurality of airfoils have been formed in one end portion of the plate, the plate is withdrawn from the working chamber and the opposite end portion of the plate inserted into the working chamber.  In another specific instance, the workpiece included a support frame in which a plurality of partially formed airfoils are mounted.  A plurality of pairs of electrodes are utilized to electrolytically remove material from opposite sides of the partially formed airfoils.  During the electrolytic removal of material from opposite sides of the workpiece to form the airfoils, electrolyte flows axially along each of the side surfaces of the airfoil from a tip end portion toward a root end portion of the airfoil.

Abstract: A gravity operated shell feed apparatus for a turret-mounted gun comprises two stacks of downwardly sloping magazine racks, from the lower ends of which shell may be singly released to roll into an appropriately positioned collection tray which is then angularly deflected in a vertical plane so as to transfer the shell to a ramming tray for delivery to a ramming position at the gun, the whole sequence being manually controlled by means of a single operating lever. The apparatus is designed for a fixed loading position thereby avoiding the necessity of sweeping the feed apparatus at high speed through a large volume of turret space, and using instead the elevating gear of the gun to sweep the balanced elevating mass through a smaller turret volume at a proportionately lower speed, in a region less hazardous to the gun crew.
